Adagio: update with external js (prebid#4217)

* Add external loader in AdagioBidAdapter

* Change adagioAnalyticsAdapter to "endpoint" type

* Change _setPredictions for a generic method

* Improve AdagioBidAdapter test coverage

* Add features detection in Adagio adapter

* Fix adagioBidAdapter tests

* Add featuresVersion field to bidRequest

* Refacto adagio.queue

* Expose versions in ADAGIO namespace

* Generate a ADAGIO.pageviewId if missing

* Move ad-server events tracking to adagioBidAdapter

* Store adUnitCodes in ADAGIO namespace

* Update documentation

Better description of test parameters.

* Add internal array to prevent empty pbjs.adUnits

* Be sure to access to window.top - does not work in safe-frame env

* Add PrintNumber feature

* Be sure to compute features on window.top

* Bump versions

* Add Post-Bid support

- ad-server events are listen in current window (instead of window.top)
- a new "outerAdUnitElementId" property is set to ADAGIO.pbjsAdUnits array in case of Post-Bid scenario. This property is the 1st parent element id attribute of the iframe in window.top.

* Set pagetype param as optional

* Add AdThink ad-server support

* Improve internal `pbjsAdUnits.sizes` detection

Use the adUnit `mediaTypes.banner.sizes` property if exists to build the `ADAGIO.pbjsAdUnits.sizes`.
The use of the `sizes` root property is deprecated.

* adagioAnalyticsAdapter: add and improve tests

* adagioBidAdapter: add and improve tests
